Bob, this helps burning through mill scale .... where short circuit does not pack as much of a “punch” .... There are definitely applications for it ...
ZILA and galvanized. Thats what i weld at work and i cant run short circuit on galv steel because it never runs smoothly. Turn that heat up some and itll burn right through.
Globular transfer in pure CO2 gives almost the best penetration profile. Better penetration than argon mix, higher welding speed, sometimes with less filler metal, less hydrogen pores, twice the volume of shielding gas, but needs higher inductive settings and better respiratory protection :)
@@carof08 there are many applications where cleanup doesn't matter, and globular is the fastest way to lay down a lot of wire and still get good penetration, and it's MUCH cheaper to run than spray transfer. Between the higher end gasses required by spray transfer, and the higher voltage and current needed, globular saves money and increases productivity. I worked in a shop that built equipment for aggregate plants, and there they used 90% globular. Who cares if there is spatter when the part is a wear surface for aggregate? Welding is just like anything else, use the right process for the given application
I’m going to be honest. We need people like you. Experienced people who love what they do. Your videos are two drawn out too much talking. The whole point of a trade school to get in and get out. Show us what we need to see. Those of us who know we can do it just need to see it.
For videos like this which seem to use one set of consumables (wire diameter and shield gas), can you guys start putting them in the video description? Once in a while I'll come back to use your videos as reference for a starting point in or troubleshooting my settings, but end up having to watch the video to confirm the wire and gas you're using (to make sure the settings are relevant). Even if you switch wires or gas during a video (which I don't think you do often), mentioning that in the description would be helpful, even without mentioning the times that you start/stop with each.
So how do you know what mode you’re in. Is it all down to the voltage and wire feed and gas with spray transfer ?is there a specific mode on the machine?
globular tranfer can add to costs, because of splatter and can cause inconsistant penetration. Buy 0.8mm, 1mm and 1.2mm (0.30, 0.40 and 0.45) wire with 82/18 ar/co2 mix and you can weld pretty much everything in SC and spray mode.
Been doing a lot of structural welding with .45 70s wire running it at 26.5 volts and 300-320 wfs it's absolutely amazing I've never MIG like this before AROUND THE SITE I CAN'T BELIEVE THE STUFF THERE DOING
I'm enjoying the education, thank you. I've tried the higher settings on my machine with .030, c25, 22V and it seemed a lot quieter, less of a popping noise and hardly any spatter. I've heard spray transfer, but only on TH-cam, and mine was almost the same same sound? I think my WFS was less, like 350-375. Strange to me.
On WeldingTipsandTricks, Jody showed that welding machines frequently don't show the correct WFS. So 350 displayed on one machine may be 315, on another machine, it may be 390. So he showed that he always measures the speed to confirm the setting. Your machine may be 15 or 20% low on the WFS, so when you thought you were cranking it up, you may have only been just getting up to spray welding speed and amps. This is why Bob keeps cranking up his speed and doing test beads. He ended up 20% higher than where he started, so the machine may not be accurately showing his WFS. Also, brand of wire affects welding performance and sounds.
I have an old Miller Passport Plus....Have not used it a lot but I really enjoy using the smaller wire ...problem is in my area when I don't use it often enough the wire quickly gets rusty.
Gulf coast of Texas here...I wrap my spools up in plastic wrap. The stuff used for packing things up for shipping. It comes on a roll with a handle and you can get it at the hardware store...probably. It helps a ton.
Never in any video do they describe what makes it a globular weld. When the amperage and wire speed cross a certain point then it becomes globular? Or is is a setting in the welder? Is it a type of of that changes it from short circuit to globular? In every video they skip the most basic description.
I am only 9 years old and the only time I ever really pull is when I stick weld, for me my welds on just about any other welding trade pushing brings the heat ahead therefore more penetration into the steel or metal of choice
Bob, I don't like to have different mig gases running around the shop, so I get as close to spray as I can with C25 a fair bit. I notice you're using some gun manipulation. I have had my best appearances with a straight drag. I'm using an old MM250 beast, and she likes to run hot and fast. But is there a particular reason you like that step and pause action? Might be why it was crowning up a bit.
Isnt globular transfer more suteable if u run 18 % co2 and u have max 220 or 200 amps to play with ? and dont have low co2 gass bottles laying around ?
saw this and see if i can help, im not an extreme expert like bob but anyhow...depending on what thickness your welding yes. Example, Say your welding 1/4 inch plates with .030 vs .035 wire, your wirespeed will be higher on the .030 than the .035 to achieve the same heat input. Wire feed speed is your heat (or amps) your putting into the weld, thicker materials need more heat input to get deeper penetration. So the thicker the plate the more WFS you need. Now if the material your welding is really thin, smaller wire like .023 may be the right choice because it runs much better at lower amps than large wire. It is easier to get a nice short arc at lower wfs than larger wires because it doesn't require as much heat to burn the wire. When welding thin materials with larger wire sometimes you are unable to turn the wfs down enough to get a decent short arc and still not burn through your materials.
Bob, Can you explain why its not easier to just get a bottle of co2 and a bottle of argon with a splitter and set your regulator flow to the correct proportion for short circuit or spray?
It just got easier. There are now cheap dual flowmeter things from China. Two flowmeters in a box it looks like. Or you can spend about four or five times more and get a mixer from Smith I think. Either one might pay for themselves pretty quickly, plus you can maybe dial things in, and get a better job every day! I want to do this myself.
The James F. Lincoln Welding Foundation book, "The Procedure Handbook of Arc Welding" likens flux core to SMAW. With that, can you take flux core into globular transfer or are you just asking for trouble? Seems like the flux would prevent the globs from forming and instead blow the wire into splatter making a big mess.
Thanks for the reply. I suppose that's something I would have learned in welding school. I looked for slow motion videos of the process and found some pretty cool stuff. This one shows the process pretty well. th-cam.com/video/MRIGks3gxG0/w-d-xo.html So with flux core, we should be running with the higher numbers like you are in this video, depending upon the thickness of our material?
There are a bunch of high-speed videos of different welding modes out there. Worth watching! Some good ones from CCWJ (Canadian Center for Welding and Joining). Might be 10,000 frames per second or so. Some of these modes look pretty awful up close and slow-motion like this. Especially when compared to new stuff like "Cold Metal Transfer", or "Surface Tension Transfer". With flux core especially it's just going everywhere, maybe 15% of the wire is going into the air, right?
I run glob different my values are 23.2-.7 195-210ipm on .035. For 2-6" sch40 to sch80 cap. It's a real steady pop.pop.pop and minimal spatter. 90/10 for the gas
Complete beginner question and please forgive me if you answered this before. Do you always do the "cursive e" motion or do you go in a straight line. What's the best for someone who is just starting.
Learn STRAIGHT mate. This weaving/circles bit is not acceptable with structural work (well not where I am anyway) and it actually gives me the heeby-jeebies.
Bob, I really like your videos, as does my MIG class (Ivytech State Collage) instructor. But we did globular today in class. We were using numbers like 18.0V, 150 WFS. Much colder than your arcs. We talked about it and neither of could figure out why the difference in setting - your hot, we're cold.. Any ideas?
Maybe this sad mode of metal transfer is associated more with straight CO2? It seems like something you get by accident, but would be interested to know of specific uses for it! There are already some comments on this below.
Das kann man so sehen. Eineige Schweißgeräte Hersteller machen das so das du bei dünnen Materialstärken der short circuit transfer hast und je weiter du in Materialstärke hoch gehest um so mehr ändert sich der Lichtbogen in einen globular transfer möglicher weise bis zum spray transfer ..... Anfangs mochte ich das nicht so sehr - ich muss aber sagen nach einiger zeit habe ich herausgefunden das das doch riesige Vorteile hat speziell fuer weniger erfahrenere Schweisser ... Der Anteil der fragwürdigen order schlechten Schweißnähte nimmt damit deutlich ab !
That's pretty much how I weld. Never knew was called globular. I just thought I liked welding hot. normally use .035 at 24V with 300 on the wire feed .Gotta change it up every now and again Depending on what you're repairing or building, With proper technique it can be done vertical up and is excellent for overhead. I've made a career doing it.
A hot short circuit and globular transfer aren't the same thing. If you are welding vertical or overhead, you definitely aren't running globular. The weld puddle is WAAAY too fluid to try anything where you are fighting gravity. Like trying to get water to stay on a ceiling. Edited for spelling

Bobs the shit...i had a teacher named...get this "Mr Miller"...i shit you not lol. Breath stunk like hell but was a great teacher. Got em scope for xmas my graduation year lol. But yea i like bob as a teacher. Hes a great dude
Wow Bob, every time I watch one of your Videos, I'm more convinced that you would be really fun to hang out with. Thank you Sir.
He is. He's much funnier in person too.
Bob is the man! Just like 690K other subscribers, sure wish he was back.
Couldn't agree more. Bob was so much better than the hipster goofballs that replaced him.
bob am glad i bought a mig machine these machines speeds up production great video

I always use globular with fcaw and push all day long awesome penetration for specially big thick projects we have at work !
FCAW OR FCAW-G ?
Good job bob
Good video. I usually understand. So I can get a q's in. Do you answer in blogs?

HI Bob great job I like your videos.
Thanks, interesting using 75/25 argon and co2 mix, and weld profile. I never Mig welded, hopefully someday. Thanks Sir
You’d have 5 million views and a hell of a name if you just showed us.
I have an old Miller Passport Plus....Have not used it a lot but I really enjoy using the smaller wire ...problem is in my area when I don't use it often enough the wire quickly gets rusty.
bigcliffe I have the same problem. I try to keep mine in my house as much as possible, but it's a pain to remove and put back in.
Gulf coast of Texas here...I wrap my spools up in plastic wrap. The stuff used for packing things up for shipping. It comes on a roll with a handle and you can get it at the hardware store...probably. It helps a ton.

I like globular transfer, but I find that pushing rather than pulling gives a nicer weld
I am only 9 years old and the only time I ever really pull is when I stick weld, for me my welds on just about any other welding trade pushing brings the heat ahead therefore more penetration into the steel or metal of choice
Pushing gives you a flatter weld but pulling gives you more penetration.

Might be why it was crowning up a bit.
Ryan Jones Man I can't straight drag to save my life. I have to rock it back n forth to regulate my speed.
Good info! So do beginners (without a teacher) do globular welds without knowing? Do you blame the "camera guy" for everything?
Isnt globular transfer more suteable if u run 18 % co2 and u have max 220 or 200 amps to play with ? and dont have low co2 gass bottles laying around ?
Great video Bob!

Thanks Bob!
I think it's especially with CO2.
You never mentioned your new jacket what’s that all about??

Where do I order the jacket from?
@southercoloradohats on Instagram.
if there is more voltage and more wirefeedspeed so you are welding with more (higher) amps ?

Shouldn't this process use 100% co2 ?
75/25 is used in short circuit mig i think .
Don't screw up your cool new jacket !!!
Why do you use 030 instead of 035
Many of us don't have 220 migs and not enough power ?
Do it....do it...
